Exercise #8:<br />
Exercise #8:<br />
In this exercise students use images, select, and audio controls.
*Play an audio file on image.onclick() using the commands: audio1.play() audio2.pause()
What Should Work:
*Using the select tool to change forms
-Play an audio file on image.onclick() using the commands: audio1.play() audio2.pause()
**Change forms using: Form1.hide(), Form2.show()
-Using the select tool to change forms:
*select1.selectedIndex()
-Change forms using: Form1.hide(), Form2.show()
*select tool indexes are 0 based
-select1.selectedIndex()
-select tool indexes are 0 based
-select.onchange() is only called if the user chooses an index other than the current selected index.
However, in the book, students are asked to use two identical select tools with “one, two” as items corresponding to the form number the user would like to navigate to. There are two forms in this exercise, so one such select tool for each form. Item “one” (index 0) is the default selected item in both forms. However, if the user selects item “one” while on Form2 to go back to Form1, nothing will happen because .onchange() is not called. The book should note that changing the default selected index in Form2 to 1 (index of item “two”) is necessary for the code to work. Currently the book just says: create a second form, put the same controls, and make the necessary changes to controls properties.
 
 
 
Exercise 9:<br />
In this exercise, students learn to save data entered to a textArea using localStorage and the JSON function.
What should work:
-TextArea’s basic properties
-Saving data entered to a textbox/ textArea:
-create an object using: Dim objectName()
-localStorage.note
-JSON.stringify([ ])
-JSON.parse(string)
-objectName.push()
-Add lines of strings to a textArea
-UBound(Array)
-vbCLRF for new line
